A dozen of circular geoglyphs of different sizes were mapped in Southern Peru in an ancient town called Quilcapampa in the Sihuas Valley. The circular geoglyphs were mapped using aerial drones, satellite imagery and ground surveys.
The most intriguing geoglyph found in the valley is in the form of circles with at least six concentric rings arranged in an irregular pattern. Other geoglyphs contain cairns or rock piles as part of the design.
What do they signify?
According to archaeologists, these geoglyphs date back to 1050 to 1400 A.D. They believe that such geoglyphs may signify the existence of bustling commerce in the area during that time. That Quilcapampa had a settlement of 70-hectare during the period and is located between the coast and the highland suggests that the town served as a junction where people and goods intersected along important trade routes.
How were they created?
Most of these circular geoglyphs were created by removing stones from the surface of the ground exposing the underlying soil layer leaving an impression of a geoglyph. While one-ring geoglyphs roughly have a diameter varying from two to four meters, some multi-ring geoglyphs are spread out over an area of 800 square meters.
Do they bear any similarity with the famous Nazca Lines?
Nazca Lines are believed to have been created by the Nazca culture between 500 B.C. and 500 A.D. However, there is no evidence that suggest any link with Quilcapampa geoglyphs created almost a thousand years later. The Nazca figures vary in complexity existing in the form of simple lines, animal figures and geometric shapes. On the other hand, Quilcapampa geoglyphs are primarily circular in nature. Moreover, Nazca Lines and Quilcapampa geoglyphs are separated by a distance of hundreds of miles negating the existence of any realistic connection.
